ABSTRACT
Walking robots are more versatile than wheeled or tracked robots, as they can easily traverse rough terrain. In this paper, we describe the development of a kinematic model for use in the simulation of three different walking gaits for a hexapod robot. We discuss the criteria for static stability using the concept of support polygons, and analyze the walking speed of three statically stable gaits as a function of the duty factor β. This simulator allows for better intuition about the performance of the hexapod using various gaits, and will facilitate future work, which will include a dynamical model, and the implementation of a simple control system to handle disturbances to the system.
